116 6 Software Instructions (PC App) Offset Correction: You can set a value for an offset correction for reading your sensor input data. This offset can be a positive or a negative number. Figure ph Alarms And Offset Screen Logging Settings: The Logging Settings screen allows you to start/stop logging on the transmitter internal memory, set the logging rate, and enable/disable the circular buffer. There are five internal logging rates you can choose from: 10 samples/seconds 1 sample/seconds 1 sample/10 seconds 1 sample/30 seconds 1 sample/minute 6-14

117 Software Instructions (PC App) 6 Figure Logging Settings Screen To start an internal logging session: 1. Select Transmitter Internal Logging to On. 2. Set the Internal Logging Sampling Rate from the dropdown menu 3. Select Circular Buffer to ON/OFF. If the circular buffer is ON, after the transmitter internal memory is full, new measurements will be overwritten over previously saved measurements starting with the oldest saved data point. This will continue until you turn the logging off. If the circular buffer is OFF, the transmitter will stop logging when its memory becomes full. Full memory is indicate by the yellow and red LEDs on the transmitter blinking alternatively. 4. Click on Save All Settings. When the transmitter starts logging internally, the green LED on the transmitter will blink twice every 3-seconds. Restore Defaults: The Restore Defaults button allows you to restore the factory default settings on the UWBT transmitter. The settings that will be restored are: sensor sub-type, engineering units, alarms and offset, and logging settings. For example, the default settings for thermocouple transmitters are: Sub type: K calibration Engineering units: F Temperature high alarm: 2300 F Temperature low alarm: -148 F Temperature deadband: 1 F 6-15

120 7 Troubleshooting/Help Section 7 - Troubleshooting/Help The information provided in this section should solve most of the common problems you may experience when operating your UWBT transmitter. If the problems and solutions outlined here do not solve your problem, please contact Omega s customer service department. Contact information can be found on the last page of this manual or by visiting omega.com 7.1 App Display Issues 1. Q: I am paired to a transmitter, but the measurement field on my display is blank. A: This may mean that the transmitter is not well-synchronized with your smart device. Switch the UWBT transmitter off and back on; then try to pair the transmitter again in the app, as outlined in the chapter titled Connecting to the UWBT Transmitter. 2. Q: The display says Open Sensor. What does this mean? A: Open Sensor means that either there is no probe connected to your UWBT transmitter handle, or the probe has not made a full connection in order to take measurements. Check the transmitter handle to make sure the connection is tight. 3. Q: Is there anywhere on the app that I can see the maximum range for my specific sensor? A: Yes. If you go to the Display Gauge view, the lowest and highest values on the gauge represent the full range for your sensor type/sub-type. 4. Q: Where is the crosshair on my graph? A: Only the playback graphs (graphs of previous logged files) allow for crosshair use. Once you ve selected the playback graph you would like to view, click within the graph and the crosshair will appear. 5. Q: I do not want the alarm sound on while collecting data, but I would like to see if I am reaching my set alarm conditions. Is there a way to see this information? A: Yes. In the Digital display, the text would change color if you reach an alarm condition (red text = high alarm, blue text = low alarm). In the Gauge display, the blue bar portion of the gauge outline represents the low alarm area, and the red bar portion represents the high alarm. In the Graph display, there are two lines added to the graph the blue line represents the low alarm, and the red line represents the high alarm. 6. Q: I have graph playback files saved on my smartphone/tablet, but cannot see them in the app. Where are the files? A: Make sure that you are not currently logging data to your transmitter or smart device. You cannot view playback files while logging. Once you stop logging, you will be able to see the files. 7-1

121 Troubleshooting/Help App Logging Issues 1. Q: Where do I find the log files that I have already saved or downloaded from the transmitter? A: The files can be found in the Display Graph View Playback Graph. A list of all of your available log files will appear, and you can select to view them from that screen. 2. Q: How do I change the timestamps on my graph from elapsed time (starts with 0:00:00) to real time (starts with the actual clock time when logging began)? A: You can change the way you view timestamps on your graph by going to Sensor Settings Time Axis, and selecting the timestamps you prefer. Selecting elapsed time means that your first timestamp will be 0:00:00; selecting real time means that your timestamps will be the actual clock times. Please note that you cannot change the time axis for a playback graph. 3. Q: I want to clear all of the logged data from my tablet/smartphone. How do I do it? A: For Android devices: 1. Go to the Settings menu of your device 2. Click on Storage Miscellaneous Files 3. In this folder, you can select and delete the UWBT files. Figure 7-1. UWBT Files On An Android Tablet 7-2

122 7 Troubleshooting/Help A: For an Amazon Kindle Fire device: 1. Go to the Settings menu of your device 2. Click on Device Options Storage 3. Click on Miscellaneous 4. In this folder, you can select and remove the UWBT files. A: For ios devices: 1. Connect your smart device to your PC, and open itunes. 2. Click on your device in the menu bar, and click on the Apps section 3. Near the bottom of the Apps screen, there is a File Sharing section. When you select the UWBT app, the box on the right will display UWBT Documents these are your stored log files 4. Select the files, and press your keyboard s Backspace button to delete. Figure 7-2. UWBT Files In itunes 5. Q: I internally logged data to my transmitter in one language; when I downloaded the log files to my tablet/smart phone, they were not in the same language. How did this happen? A: If you have internally logged data to the transmitter, the log file will always load in the language you are using on the UWBT app at the time of download. For example, you may internally log data on the UWBT transmitter in English. However, if you changed the app s language to French, and then proceed to download the log file, it will download in French. 6. Q: If my internal memory is full, but I choose to use a circular buffer, what happens to my existing data? A: As you start logging new data, the UWBT app will delete and overwrite the existing memory as time passes. You will not lose all of your data at once. 7-3
